Skid preventing devices for automotive vehicles



E. DORE June 5, 1956 SKID PREVENTING DEVICES FOR AUTOMOTIVE VEHICLESOriginal Filed April 16, 1952 INVENTOR. 5142M! .0095 BY ATTOP/Vf) UnitedStates Patent 2,748,826 SKID PREVENTING DEVICES FOR AUTOMOTIVE VEHICLESEvelyn Dore, New York, N. Y. Application July 15, 1955, Serial No.522,296 2 Claims. (Cl. 152-179) This invention relates to anti-skiddevices for vehicles, and more particularly for rubber tired motorvehicles.

As is well known, one of the greatest dangers to which motorists aresubjected is the skidding or side slipping of an automobile on icystreets or highways. If the ice is hard and smooth, the usual tirechains afford but little protection against side slip.

The general object of the invention is to provide an attachment whichmay be applied to existing motor vehicles, and which will effectivelyprevent any side slip of the wheels when traveling over icy surfaces.

Another object of the present invention is the provision of a device ofthe character described which is provided with a snow tosser as well aswith an ice cutter, so that snow and ice particles will be tossedlaterally away from the vehicle thus preventing accumulation of snow andice under the fenders to such an extent as to avoid friction thereon ofthe rotating wheels.

A further object of the present invention is the provision of a deviceof the character described which is adjustable and resilient to acertain extent, so that a device constructed in accordance with thepresent invention can be used on tires of different sizes.

Yet still another object of the present invention is the provision of adevice of the character described which can be attached to, and removedfrom, a wheel easily and quickly as well as without any considerableamount of effort or skill, and which is simple in construction as wellas comparatively light in weight, but which is also sturdy, durable andwell adapted to withstand the rough usage to which devices of this typeordinarily are subjected.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawing a preferred form of the invention has beenshown.

In said drawing:

Figure 1 is a side view of a preferred embodiment of my invention,

Fig. 2 is a bottom plan view of the same, and,

Fig. 3 is an enlarged fractional sectional view on the line 3-3 of Fig.1.

Similar reference characters refer to similar parts throughout theseveral views.

In the drawing the numeral 2 denotes a pair of substantiallysemi-circular channel members of a rubberized fabric material or of anyother suitable flexible and (or) elastic material, which aresemi-circular in cross-section and adapted for fitting around the treadsurface as well as over the major sections of the side portions of atire 4 of an automotive vehicle. A pair of substantially semi-circularplates 6, whose outer edge portions are provided with serrations 8, aresecured to the lateral portions of each member 2 by means of rivets orthe like.

Although the parts 2 and 6 can be fastened to the wheel by any suitablemeans I prefer to secure them thereto in the manner shown in thedrawing, where it will be seen that the ends of the plates 6 areprovided with lug portions 12 into which are hooked the hook-shaped ends2,748,825 Patented June 5, 1956 of tension springs 14. This arrangementpermits to attach the parts 2 and 6 to a tire 4easily and quickly byplacing the parts 2 around one tire 4, expanding the springs 14, hookingtheir ends into the lugs 12 and releasing the springs 14. Similarlysimple is the detaching of the parts 2 and 6 from the tire 4. Since theparts 2 are flexible and somewhat resilient they can be used on tireswhich vary as to size to a certain degree.

I prefer to provide the parts 2 with a plurality of protruding elements,such as nails 16, whose heads are preferably provided with slots 18(Fig. 3) and reduced toward the top. These protruding elements also maybe protruding rubber elements or the like. Furthermore, I prefer toextend diagonally across those portions of the tire 4 which are notcovered by the members 2 toothed bars 20, which are detachably securedto diagonally opposite portions of the plates 6 by means of screws 22and wing nuts 24 or the like.

In operation, the serrated plates 6 will cut into the ice, the nails 16will prevent skidding, and the bars 20 will toss some of the snow andice particles laterally away from the vehicle.

Since certain changes may be made in the above article and differentembodiments of the invention could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention which as amatter of language might be said to fall therebetween.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent is:

l. A skid preventing device for automotive vehicles comprising a pair ofresilient, substantially semi-circular members adapted for encompassingsections of the outer portion of a tire, resilient means engaging theends of said members tending to force said members toward each other, aplurality of protruding elements provided at the outer side of each ofsaid members, semi-circular plates having serrated edge portions beingsecured laterally to said members, and toothed bars diagonally extendingover the end portions of said members having their ends detachablysecured to diagonally opposite end portions of said semi-circularplates.

2. A device of the character described comprising a pair of elastic,semi-circular members being substantially semi-circular in cross-sectionand adapted for encompassing sections of the tread surface as well aslateral portions of a tire, a pair of semi-circular plates havingserrated edge portions being secured laterally to each of said members,tension springs detachably secured to the ends of said semi-circularplates tending to pull the same toward each other and to press saidmembers firmly around the tire, a plurality of taper members in spacedrelation to each other being secured to and extended beyond the outerside of said semi-circular members, and toothed bars diagonallyextending over the end portions of said members having their endsdetachably secured to diagonally opposite end portions of saidsemicircular plates.
